  • The researches conducted in 2013 were categorized in 6 parts as follows.
    1. The fate of pathogenic microbes in composting toilet was investigated using molecular biological approach. And the value of compost was also investigated.
    2. The dependence of wavelength on UV inactivation of coliphages and heterotrophic bacteria were investigated with high accuracy.
    3. Rapid water quality analysis was suggested by applying fluorescent analysis focusing on humic substance characterization.
    4. The parameter used in the forecasting model of industrial water demand was analyzed and the driving factors were investigated.
    5. New meter of water flow was developed and it was used in the field research in Hanoi to obtain the domestic use on each purpose.
